MC Helios-44-3 58mm f/2 lens for M42 Zenit Pentax Practica

HELIOS-44-3 is a standard multi-coated (MC) lens for Soviet SLR 35 mm Zenit cameras. The lens can be fitted on the M42 Pentax cameras. First HELIOS-44 lenses were borrowed from Carl Zeiss BIOTAR lenses and issued since end of 1950th years in M39, then in M42 screw mount, and had not very good glory because were with low contrast in common... But latest versions of HELIOS-44 lens became very sharp. This famous lens was manufactured in the USSR, and features outstanding sharpness, contrast and color rendition. I saw photos taken with similar lenses several times before and I appreciated excellent pictures quality. In the main, most all Soviet and Russian lenses are exceptionally good and this one is no exception! It can be used with a lot of digital Micro 4/3 cameras with simple and inxpensive adapter. ITEM'S CONDITION: EXCELLLENT+++++ The glass is very clean, lens looks never used before. Focusing and aperture are smooth. Aperture leafs show very minor oil signs, even it is a usual feature for a lot of Russian lenses. Cosmetically lens looks in fine condition, just examine item's photo please. All functions are available. * Focus 58 mm. * Angle of view about 42 degrees. * Relative aperture 1:2.0 (up to 1:16 with clicks). * Additional ring for fast closing aperture from full opened to preinstalled meaning. * Lens mount M42 (known also as Pentax Screw Mount), same with huge quantity of lenses for old Practica, Pentax, Yashica, Cosina and other cameras with optical registration 45.5mm. * Mounting for modern SLR & dSLR cameras will not bring any trouble with well-spread M42 adapters. * The lens is well-applicable for digital cameras with micro 4/3 system and other with working distance 45.5mm and less, with the use of adapters: All Sony NEX, Olympus, Panasonic: Lumix DMC-G1, DMC-GH1, DMC-GF1, DMC-G2, DMC-G10, Epson, Samsung and other. * Some Helios 44-3 lenses have a focusing ring where the back edge projects past the base of the lens where the M42 screw begins. Once the lens is mounted on the camera, this prevents the focusing ring from rotating back to full infinity focus. I tested the lens with Canon lens adapter and had no any troubles with the focusing. I hope it will work with other adapters too. * Focusing from 0.5m. * Scale of distances in meters. * Filter mount M 52.5x0.75mm. * The lens was made at Vavilova plant at the city of Minsk in Byelorussia in 1990.
